I have a Nissan Altima and Frontier, both with the 2.5L engine. I am looking at the Mobil 1 0W30afe and 5W30 for my oil. I want an oil to use year round and want the best oil for immediate start up flow, especially in winter. The lowest temperature I see is around 10 degrees Fahrenheit. I can not find any real information about whether the 0W30 would flow faster in the low temperatures I get versus the 5W30. I see both weights are very close at 40 and 100 degrees celsius. I can find no real reliable information for temperatures such as 32 degrees or even 0 degrees Fahrenheit in relation to the two weights and viscosity. It would seem the 0W30 would flow faster the lower the temperature gets, but I do not know if there is much difference or how much there is at the coldest temperatures I see in my area.
I would appreciate any information and suggestions I can get to make a good decision. Thanks.
